Checking the Engine Deck Height
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Adjust the tire pressure in the
rear tires to specifications; refer to
Drive System Maintenance (page 33) .
4. Measure engine deck height at location A (Figure 69).
5. Measure engine deck height at location B (Figure 69).
6. If the height at location A and B are not the same,
change tire pressure slightly to make them the same.

Checking the Carrier Frame
Front-to-Rear Pitch
The carrier frame must have a pitch between 1/8 inch
(3 mm) to 3/8 inch (9 mm) over the length of 24 inches
(61 cm) on the carrier frame (Figure 70).
1. Measure out 24 inches (61 cm) on the carrier frame
(Figure 70).

4. Same height at locations
A and B
1. Carrier Frame
2. 1/8 inch -3/8 inch (3-10
mm) pitch over 24 inch (61
cm) length
3. 24 inches (61 cm)
2. Measure carrier frame height at location A
(Figure 70).
3. Measure carrier frame height at location B
(Figure 70).
4. The height at location A must be an 1/8-3/8 inch (3
mm -10 mm) lower than location B (Figure 70).
5. If the carrier frame is not correct, move caster
spacers to make it an 1/8-3/8 inch (3 -10 mm) pitch
(Figure 70). Move spacers from top or bottom to
make the correct pitch.
6. The tire pressure may also be adjusted slightly to
make an 1/8-3/8 inch (3 -10 mm) pitch.
Checking the Carrier Frame
Side-to-Side Height
The carrier frame needs to be parallel side-to-side from
the ground.
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Adjust the tire pressure in the
rear tires to specifications; refer to
Drive System Maintenance (page 33) .
4. Measure carrier frame height at location A
(Figure 71).
5. Measure carrier frame height at location B
(Figure 71).
6. If the carrier frame height is not the same move
spacers from top or bottom of caster wheel, to
make it level. The tire pressure may also be adjusted
slightly to make it level.
